2 Claims.

This invention relates to new and useful improvements in windowstructures and the primary object of the present invention is to providea bot.- tom window sash including a plurality of vertical- 1y swingingwindow frames or closure members.

Another very important object of the present invention is to provide abottom window sash composed of a group of vertically rotatable frames soconstructed as to permit a single operator to be employed forsimultaneously rotating th frames.

Another object of th present invention is to provide a window structureincluding a plurality of vertically rotatable window frames and a singlesliding bar for rotating all of the frames upon sliding of the bar.

A further object of the present invention is to provide a windowstructure including pairs of vertically rotatable window frames andinterlocking and sealing means between adjacent frames when the framesare in their closed position.

A still further aim of the present invention is to provide a windowstructure that is simple and practical in construction, strong andreliable in use, neat and attractive in appearance, convenient tooperate, inexpensive to produce, install and service, and otherwise welladapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein likenumerals refer-to like parts throughout, and in which:

in for the purpose of sash l2.

illustration, there is disclosed a preferred embodiment of the presentinvention, the numeral It represents a substantially rectangular mainwindow casing having the upper half of the opening therein closed by anupper 'Ihelower half of the opening in the window casing Ill is closedby a bottom sash Hi.

The bottom sash I4 is composed of an auxiliary window casing I '6 havingvertical side pieces or rails l8 whose lower ends extend below the lowerhorizontal rail 20 of th casing Hi. The bottom sash also includes a.plurality of window frames or closure members 22, 24, 26 and 28.

Anchor plates 30 are secured to the lower horizontal edges of the frames22, 24, 26, 28 and support vertical pivots or trunnions 32 that arelocated intermediate the vertical side edges of the respective frames onwhich they are mounted.

Additional trunnions or pivots (not shown) depend from the upper rail ofthe casing l6 and enter recesses (not shown) in the upper horizontaledges of the frames 22, 24, 26 and 28.

The trunnions 32 depending from the lower horizontal edges of the windowframes extend through and below the rail 20 and include reducedexternally threaded ends 34 that enter longitudinally spaced slots 36provided in an actuating member or bar 38. An arm 40 is mounted on theend 34 of each trunnion 32 for rotation with the trunnions and thesearms project laterally from the trunnions and are located beneath therail 26.

Pit-mans or links 42 are terminally pivoted to the I armsfifi and theactuating member 38 so that, asthe actuating member i movedlongitudinally all.

of the. window frames will r t e or swing about their vertical axes.

The arms 40 are secured to the trunnions depending from the lower edgesof the frames by any suitable means such as nuts 43 threaded on the ends34, and washers or spacers it received on the ends 34 space the arms 40from the links 62, the link 42 from the member 38 and nuts 46 threadedon the ends 34 from the member 38.

Means is provided for moving the member 38 longitudinally to selectivelyopen or close the win- This means consists of a channel bracket 48mounted on the lower edge of the rail 20 that functions as a guide sinceit slidably receives the member 38. An operating shaft 58 is journaledfor rotation in registering openings in the leg portions of th bracket18 and supports a gear 52.

A portion 54 of the member 38 is ofiset and is provided with a pluralityof spaced parallel, transversely extending slots or recesses 56 forselective- 1y receiving the teeth of the gear 52. The web of the bracket48 is reinforced and strengthened by an anchor plate 58. A suitable handgrip 60 is secured on the shaft 50 to permit the shaft to be manuallyrotated.

Spring weather strips 62 are mounted on the upper edge of the rail 20and the lower edge of the upper rail of the casing l6, and these stripsare biased between the upper and lower rails and the frames 22, 24, 26,28 to yieldingly retain the frames in a selected opened position and toclose the spaces between the upper and lower rails and the upper andlower edges of the frames. A resilient closure or concealing strip 64 ismounted on the outer edges and between the lower ends of the side piecesl8 and also on the rail 20 and the inner edges of the side pieces arejoined by a window casing C to conceal the actuating memher, the gear,the arms and the link. The lower rounded or flared edge 66 ofthe strip64 will yieldingly bear against the window sill 68.

The outer side edges or vertical edges of the frames 22 and 28 arerabbeted to interlock with the rabbeted side pieces I8 of the casing I8.The inner vertical edge of the frame 22 is provided with a vertical ribor tongue in for entering a vertical groove or recess I2 in one verticaledge of the frame 24. The inner vertical edge of the frame 28 isprovided with a vertical groove or recess 14 for receiving a verticalrib or tongue 16 on one vertical edge of the frame 25 so that the frames22 and 24 will be sealed together and so that the frames 26 and 28 willalso be sealed together when the frames are closed.

The adjacent vertical edges of the frames 24 and 26 are provided with avertical rib or tongue 18 and a vertical groove or recess 80respectively. When the frames are closed, the tongue 18 will enter thegroove 80 to seal the frames 24 and 26.

Additional weather stripping may be used between adjacent frames and theframes and the casing H in order to prevent cold air passing through thewindow structure when the frames are in their closed position.

It should be noted that the arms 40 and the links 42 are so arranged asto permit all of the window frames to swing to an open position as thebar 38 is moved to the right, as shown in Figure 5, and to their closedposition as the bar 38, in Figure 5, is moved to the left.

In practical use of the present invention, as the shaft 50 is rotated tomove the bar 38 to the right, the links 42 associated with the trunnionson the frames 22 and 26 will pull the arms 40 associated with the sashes22 and 24 to urge the frames 22 and 28 to an open position, and at thesame time the links 42 associated with the trunnions for the frames 24and 28 will push the arms 49 associated with the frames 24 and 28 tourge the frames 24 and 28 to an open position. The opposite procedure isfollowed when the bar 38 is moved to the left with the links 42associated with the frames 22 and 26 pushing the arms 40 associated withthe frames 22 and 26 and with links 42 associated with the frames 24 and28 pulling the arms 40 associated wth the frames 24 and 28.
